A puzzling plant to place. It differs from Poa mainly in the flowering glumes 
being rounded on the back, and minutely 3-toothed (or irregularly erose) at the tip. 
It agrees with Atropis in the flowering glumes being rounded on the back, but differs 
in habit and in the 3-toothed tip of the flowering glume. Aithough it is not a typical 
Triodia, it must be kept in the vicinity of the New Zealand 7’. australis, which is its 
nearest ally. ful )

Perennial or annual grasses. Leaves narrow ; ligules hyaline. Spikelets 
2-5-flowered with the uppermost flower sterile, laterally compressed, 
shining, densely crowded in spike-like panicles; rhachilla disarticulating 
above the outer glumes and between the flowering glumes, produced 
beyond the uppermost flower. Two outer glumes persistent, empty, 
unequal, keeled, acute or acuminate, margins hyaline. Flowering glumes 
exceeding the outer glumes, with broader hyaline margins, 3-5-nerved, 
entire or bifid, acuminate or mucronate or shortly awned. Palea white 
and hyaline, 2-toothed. Lodicules 2. Stamens 3. Styles short, distinct ; 
stigmas plumose. Grain oblong, laterally compressed, free within the 
flowering glume and palea. 
Species 12 or 15, mainly in the temperate parts of the Northern Hemisphere, rarer 
mn the South Temperate Zone. The single New Zealand species is also found in South 
merica. |

Culms densely tufted, erect, slender, glabrous or pubescent, 6-24 in. high. 
Leaves crowded near the base of the culms, 2-9 in. long, 4-hin. broad, 
flat, soft or almost flaccid, glabrous or more or less pubescent, sometimes 
almost villous; sheaths long, rather tight, striate, pubescent or villous ; 
heules short, truncate, ciliolate. Panicle 1-5 in. long, cylindric, usually 
dense and spike-like, but sometimes irregularly interrupted or lobed ; 
branches short, erect, minutely villous-pubescent. Spikelets pale-green or 
pale purplish-green, shining, about #in. long, 2-3-flowered. Two outer 
glumes broadly lanceolate, hyaline, acute, 3-nerved, often scabrid on the 
keel. Flowerimg glumes oblong-lanceolate, glabrous or minutely rough
